Use the principles of heat transport to explain why (for the same latitude) ocean temperatures heat and cool by only 2-4 degrees Celsius per day, while desert temperatures may change by more than 20 degrees Celsius per day. The differences in temperature change per day between desert and ocean temperatures can be attributed to differences in heat conductivity and specific heat capacity of sand and water. Energy is exchanged between the surface of the earth and the air immediately above the surface of the earth through conduction. The type of surface and properties of the surface can heavily influence the surface air temperature. Both desert and open-ocean will

The energy required for evaporation or condensation reduces the amount of heat energy being exchanged with the air and thus reduces the temperature extremes. Water is a much better conductor of heat than sand, which leads to more energy from solar radiation being distributed throughout large depths of water in the ocean. Energy is further distributed throughout the ocean by the constant mixing and movement of liquid water. This distribution of heat energy leads to little energy being transferred back to the surface atmosphere. Sand is a poor conductor of heat, so heat does not distribute throughout sand particles beneath the surface and sand does not mix in the way water in the ocean does. Sand more quickly absorbs solar radiation and then transfers this heat to the surface atmosphere, which causes the surface atmosphere to have larger temperature variances. Water has properties, high relative specific heat and high relative thermal conductivity, that allow it to absorb much more solar radiation than sand. Because water absorbs much more of this heat energy it does not transfer as much heat to air directly above it through conduction as sand does. This means that the temperature of the surface temperature air over the ocean will not vary as much as the surface temperature of the air over a desert.
Describe the diurnal temperature cycle, with reference to the typical daily radiation budget, with the time of day that we would
3. Based on your answers, why is it warmer in summer than in winter? It is warmer in the summer then in the winter because the Earth’s tilt is
The release or agitation of the water would release the co2 causing the water to rise and evaporate.
5. A) What would you expect to happen to the temperature on Earth if the amount of energy radiated by Earth increased but the amount coming from the Sun stayed the same?
For my three locations the surface temperature was greater than the air temperature. I would expect that because the surface is absorbing
The climate of a certain area can change physical or chemical properties of almost anything. For example if you moved ice from a cold climate to a warm climate then the ice would physically change into water. Another example is if you put cake batter into a hot oven it will turn into cake after a specific amount of time. These types of changes can happen over long periods of time or suddenly. Generally, with data from previous studies, heat tends to make things spread out or get looser; the molecules tend to spread out in warmer situations. Cold has the tendency to make the molecules in different objects come closer together and become tight and not very flexible. For example the molecules in water when its warm are much further apart in its liquid state of matter compared to how close the molecules are when its cold are much closer together. Thermodynamics is the branch of physical science that deals with the relations between heat and other forms of energy and relationships between all forms of energy. There are four laws of Thermodynamics that talk about the relations with heat and other forms of
When comparing Data Set 3 & 4 to Data Set 5 & 6, there is a clear and direct relationship. In 3 and 4, the CO2 levels have an effect on the average global temperature (if CO2 levels increase, average global temperatures increase). In 5 and 6, as ice caps melt more and more, the difference in average surface temperature of the ocean increases. The effect that Data Sets 3 and 4 has on Data Sets 5 and 6 is that as the CO2 levels increase, the temperatures increase as well. As the temperatures increase, ice cap volume decreases which leads to the increase of the average surface temperature of the ocean. Also, the increase in global average temperature also affects the difference in average surface temperature of the ocean. This is so because as
This deflection of sunlight, and more importantly the solar radiation, keeps the heat off of the earth. This breaks up the constant bombarding of heat that comes from the sun that breaks down the atmosphere. Basically, the more moisture that is up in the clouds, the more that it will cool the earth. Because green phytoplankton release a chemical that brings more moisture into the clouds, they help cool the earth by proxy.
Ocean circulation patterns influence global climate by distributing heat, moisture and CO2. The North Atlantic Deep Water (NADW) is a process that mixes warm water with cold water. The efficiency of this current depends on its density and salinity. The changes
A desert is the driest of all the biomes, receiving, on average, less than 10 inches of precipitation per year. Deserts cover about one fifth of the Earth's land surface and can be classified as hot and dry or cold deserts. The hot and dry deserts are located near the Southern or Northern Tropic, and, just as their name suggests, can receive extreme temperatures of 43-49°C during day and usually have very little rainfall and/or concentrated rainfall in short periods
Oceans absorb most of the sun’s radiation compared to the atmosphere and land surface. Movement of the heat through local and global ocean currents affect the regulation of weather and temperature conditions. Understanding the essentials of the ocean 's circulation has advanced during the past decades and scientist are able to model and find new data on past climates. Oceans move an extensive amount of heat across the planet in the same amount as the atmosphere. The difference is the oceans are confined by land masses so its heat is channeled into specific regions. Ocean currents are located at the surface and 300 meters deep below the water. Currents are powered by wind, tides, the Earth 's circulations, the sun (solar energy) and water density. These characteristics affect the shape, size, directions and speed of ocean currents.
One published primary literature showcased how the amount of heat transferred to the environment increased as the environmental temperature decreased. The study showed small endotherms, such
Energy from the sun drives the earth’’s weather and climate, and heats the earth’’s surface; in turn, the earth radiates energy back into space. Atmospheric greenhouse gases (water vapor, carbon dioxide, and other gases) trap some of the
Temperature is a major determining factor of global climate patterns. It affects the life cycles of plants and animals, influences weather and tides, and controls the freeze and thaw of the polar ice caps. A small change in average temperature can have powerful effects on the environment worldwide. Salinity helps us understand the health of a water body, and what animal and plant species we expect to find (or not find) there.3 Some animals tolerate changes in salinity well, and are found in both freshwater and salt water (eels, alewives, invasive Chinese Mitten Crabs). Others are healthy only when living within a certain range of salinity (oysters). Oceans are4 the lifeblood of planet Earth and humankind. They flow over nearly three-quarters of our planet, and hold 97% of the planet's water. They produce more than half of the oxygen in the atmosphere, and absorb the most carbon from it.
(Luedeling et al., 2009b) probed decline in winter chilling hours in mountain oases of Oman. In the model adopted , measurements in oases and the high resolution record was used to calibrate the long term record of daily temperature . In order to model hourly temperature , minimum and maximum daily temperature were used because their occurred a substantial shift in the ratio of the difference between maximum and minimum temperature and the difference between mean and minimum temperatures in Saiq over the period of 2003 to 2004 . Day length (solar radiation ) was used in order to estimate the different sunrise and sunset timings throughout the year. Time period for the estimation of records was 1979 to 2008 .Further , the temperature of each hour was estimated since 1979 , using regression equation , which was based on the long term daily minimum and maximum temperatures.
In most deserts, it’s usually around 120 degrees fahrenheit during the day and only gets down to 70 degrees fahrenheit during the night. Most deserts get less than 10 inches of rain every year, but some deserts get even less than that. The wind is constantly blowing in deserts. The wind speed in deserts is annually around 80 miles per hour. The wind is the main reason that so many people get lost in deserts, because it is always reshaping sand dunes and covering up landmarks with sand (Johansson, 14-16).
